Custom logging settings for task execution

[Massimo Schiavon]

I want to set the hadoop.root.logger variable for task executions but 
seems that this setting is hardcoded at line 352 of TaskRunner.java

[...]
vargs.add("-Dhadoop.root.logger=INFO,TLA");

[...]

there is a way to add a custom appender?

I need to do this because I want to pipe the log stream to syslog ant 
then to Flume

Thanks
Massimo
